Built to Hold Depth Longer and Farther
An extended 40 ft Type 6 sinking head and intermediate running line keeps your fly down through the full retrieve, built for large, deep water where distance and depth matter.
Designed for streamer fishing in rivers, the Rock Bottom targets trout holding in softer current seams, moderate depth, and structure where a slower sink keeps flies in the zone longer. Its compact 40 ft Type 6 sinking head delivers large streamers with control, while the intermediate oversized running line improves handling, connection, and strip-set control.

Used this line for river streamer fishing and found it excellent for reaching deeper zones. The sink rate is steady and keeps the fly in the strike zone longer. Easy to handle and works well with larger streamers.
Frank Brown –
Good depth performance in moderate current. The line stays down well and gives better control during strip sets. A bit longer than expected, but worth it for deep water fishing.

Perfect for targeting trout in deeper river seams. The 40 ft sinking head gives me more reach and the running line is sturdy and responsive during casting.
